Introduction: Rectus sheath hematoma is a rare but an important clinical entity in the differential diagnosis of abdominal pain. It is often a self-limiting condition that can be managed successfully in conservative measures. If not recognized, it can lead to unnecessary emergency surgical procedures. A 55-year-old male patient suffering from chronic renal failure and cardiomyopathy presented with a progressively growing abdominal mass diagnosed to be a bilateral rectus sheath hematoma. Despite many complications related to alteration of general status, electrolyte imbalance and coagulation problems, conservative management proved successful, while prompt surgical intervention could have ended in death in such a fragile patient.
